I from Mongolia, which is EU region by Battle.net. When I see payment options I only see RUB there. But we don't use RUB (russian currency). So problem is, since i don't have RUB visa card, I only can pay USD. But if I change my region into US, price will become 39$, almost 4 times expensive than RUB payment option.
So my question is, can I put some USD in my card and purchase game from Blizzard which is price in RUB? They convert it?
EDITED/ADDED When I use both EU, and US sites, prices are different. https://eu.battle.net/shop/en/product/starcraft-ii-wings-of-liberty https://us.battle.net/shop/en/product/starcraft-ii-wings-of-liberty
On EU its 499 RUB (14$), on US its 39.99$. Why price have this much difference? Don't you think everyone buy cheaper one from eu.battle.net? Also I wonder If I buy from EU.battle.net will they give me only Russians usable client?
